operation known to printers as the action of putting together into one solid mass that which is to be printed. This mass generally consists of type or electros, surrounded with wood furniture, placed inside of a metal frame called a chase, and wedged in tight with wedges which are called quoins.

Furniture of this kind, as commonly used in printing establishments, is generally made of blocks of wood. The objection to such furniture is that it is very greatly affected by atmospheric changes, and also by solvents used towash up the form during and after printing, so that the blocks swell or warp and are no longer true,an essential, if good printing is to be done. As a consequence of this distortion, the face of the type will not be in a true plane, a condition called off its feet with the result-so frequently seen in printed matter-that there will be portions of the print so faint as, to be almost illegible; or, if the block is swollen, as sometimes happens, it will receive some of the ink from the roller, and a smudge will appear on what should be a clean margin.

Another objectionable feature is when the furniture is warped this causes the form to acquire a bend or spring in itself and the action of the form on and off the impression acts exactly as a spring on the bed of the press, and sometimes air will be trapped between the bed plate of the press, and thetype and furniture held by the lock-up; then when the impression is put on it again (this action taking place at the rate of from 1,000 times an hour and upwards, according to the style of the press,) a condition arises called work-ups, which is the action of the air trying to escape through the place which offers it the least resistance, which is the spaces between words or around illustrations,

forcing them up tothe line of impression and printing black spots as if it were type, there byruining the quality of the printing.

' My invention has for its object, to produce printing furniture which will not swell or warp, and hence will not be susceptible to moisture or to atmospheric changes, and which will be so shaped as to prevent or avoid any tendency to distort the plane of the type,

and also will be provided with escape of any trapped air.

A concrete embodiment of my invention is illustrated in the accompanying drawing, to be considered as a part of this specification, in which- Fig. 1 is a perspective view of a my improved printing furniture;

- I Fig. 2- isa longitudinal sectional View;

'Fig. 3 is a side view; and

Fig. 4 isv an end view, on'slightly reduced scale. 1

Similar reference numeralsrefer to similar parts throughout the entire description.

As shown in the drawing, my printing furniture is composed ofblocks, the sides 1 and 2 of which are milled away, providing continuous grooves 8 and 4. The edges of the grooves 3 and 4 form shoulders 4, 5, 6 and 7 which are designed to abut the type when in the frame (not shown). I also form grooves V 9 and 10 in the edges of the blocks. The edges of these grooves 9 and 10 also form ports 7 forthe piece of shoulders 11, 12, 13 and 14, the continuous grooves cut'on the top and bottom give the appearance of feet to the furniture when seen as shown in Figs. 1 and 4 of the drawing and provide for two contact points so that whateverrough handling the furniture may get which 'will tend to round the edges of these' shoulders, the furniture will still maintain itsvertical position and will notwabble,

in the form, as would a piece-ofrwood furniture that iswarped, will, as it is'has only one contact point. .1

By milling the grooves on both the top and 1 NT oFrIcE bottom either side can be used for the base. The grooves on the sides are also made so as to give two contact points to the sides of the form and acts as a double grip again no matter how rounded off the edges may get from rough usage. the furniture will still retain this all important feature. When wood furniture acquires rounded edges it loses its grip on the form due to there being but one contact point and that on only a small surface of the side making a form the prey for loose type workups and type ofi-its-feet. V

In the body of the block I provide a plurality of apertures 8 of suiiicient area to entirely avoid any possibility of there being any trapped air, thus eliminating the danger of the face of the type being moved out of a 7 true plane. 7

The blocks are made preferably of some synthetic material which is not susceptible to atmospheric changes, though obviously they may be made of'fiber or similar material which will not swell or warp when in damp weather.

Having described my invention, what I regard as new, and desire to. secure by Letters Patent of the United States, is:

1. Furniture for printing, comprising .a

i blockiormed of material impervious to the weather, there being continuous parallel grooves on the sides and edges of said block which extend from end to end and a plurality of apertures therethrough, and shoulders on the top, bottom and sides of said block adja-- cent the edges of said grooves, for the purpose set forth substantially as described.

2. Furniturefor printing, comprising a block formed of synthetic material, there being continuous parallel grooves on the sides and edges of said block which extend from end to end and a plurality of apertures therethrough, and shoulders on the top, bottom and sides of said block adjacent the edges of said grooves, for the purpose set forth substantially as described.

8. Furniture for printing, comprising a block formed of material impervious to the weather, there being continuous parallel grooves on the sides and edges of said block which extend from end to end, and shoulders onthe top, bottom and sides of said block adjacent the edges'of said grooves, for the V purpose set forth substantially as described.

r 4. Furniture for printing, comprising a block, and outwardly projecting parallel shoulders on the sides and edges of said block which extend from end to end of said block, said block having ports for the escape of entrapped air. I

edges of said block, said block having ports for the escape of entrapped air.

6. Furniture for printing, comprising a block formed of material impervious to the weather, and outwardly projecting continuous parallel shoulders on the sides and edges of said block which extend from end to end of such block, the said block having ports for the escape of entrapped air.
